Hi all,

I would very much appreciate it if we could get some eyes on the following pull requests:

• Add a cookbook recipe for a multipanel phase plot: https://github.com/yt-project/yt/pull/1605

• Make covering_grid work with yt's parallelism: https://github.com/yt-project/yt/pull/1612

• Automatically set up particle filter dependencies: https://github.com/yt-project/yt/pull/1624

• Improvements for the WarpX frontend: https://github.com/yt-project/yt/pull/1634

• Improvements for the quiver callback: https://github.com/yt-project/yt/pull/1636

• Use python_requires in yt's setup.py: https://github.com/yt-project/yt/pull/1640

• Fix bug related to dataset caching in the tests: https://github.com/yt-project/yt/pull/1643

All of these are passing the tests and are ready to merge in my opinion. However, I don't want us to get into a situation where only one person is regularly reviewing code. It would be really nice if one or two of you could go through this list and give all these pull requests a review. If you don't have time for that, just look over the ones that strike your interest.

Thanks very much for your help!
